研究了Na2 B4 O7添加剂对Fe2 O3+Al体系离心SHS陶瓷内衬钢管压剪强度的影响。结果表明 ,添加Na2 B4 O7后 ,Al2 O3和Fe两相之间的界面张力降低 ,导致Al2 O3和Fe两相在离心力作用下分离不彻底和润湿性改善 ,结果陶瓷衬管的压剪强度显著提高
The effect of Na2B4O7 additive on the compressive shear strength of centrifugal SHS ceramic lined steel tube with Fe2O3 + Al system was studied. The results showed that the interfacial tension between the two phases of Al 2 O 3 and Fe decreased after the addition of Na 2 B 4 O 7, resulting in the incomplete separation of Al 2 O 3 and Fe phases under centrifugal force and the improvement of wettability. As a result, the compressive shear strength Significantly increased
